除了if之外,是否還有其他的連詞也可以引導條件狀語從句呢? 回答是肯定的。由于這些詞出現(xiàn)的頻率較小,且用法較復雜一些,所以不如 if 為大家所熟知。

下面,小編就為大家就這些詞的用法以例句的形式進行一下簡單總結。

?

1、unless conj.除非,若不,除非在……的時候

The targets would not be achieved unless other departments showed equal commitment. 除非其他部門同樣努力,否則這些目標無法達成。

Training is worthless unless there is proof that it works.? 除非能證明訓練有效,否則就是白搭。

?

2、on condition(that)...在……條件下,如果 on condition (that)...引導的條件從句是主句事件發(fā)生的前提條件或唯一條件。

He has been granted his freedom on condition that he leaves the country.? 他已獲準恢復自由,條件是他離開這個國家.

I will grant you pardon, on condition that you help me solve a terrible problem.? 我愿意饒恕你,但是你要幫助我解決一個十分棘手的問題.

?

3、supposing conj.如果,假如 supposing引導的條件從句表示一種假設條件。

Supposing he's right and I do die tomorrow? Maybe I should take out an extra insurance policy.? 假設他是對的,我確實明天就會死,那該怎么辦?也許我應該再買一份保險。

Supposing by a freak the Tudsburys did show up in Honolulu?? 沒準兒突然之間塔茨伯利父女倆真的在檀香山出現(xiàn)了呢 ?

4、provided conj.假如,除非,以……為條件 provided (that) +從句表示一種假設條件。

Provided you didn't try to make sense of it, it sounded beautiful.? 只要不非得弄懂它的意思,它聽上去還是很美的。

He won't be against us in the meeting provided that we ask for his advice in advance.如果我們提前征求一下他的意見,他就不會在會上反對我們。

從上述例句可以看出 if, unless, on condition (that), supposing, provided 等詞引導的條件狀語從句,主從句條件關系分明,結構清晰。希望大家認真理解記憶~
